POSEIDON M28 USER MANUAL
Use USB port with at least 1.5 A
for normal charging
The M28 charger cable has a standard USB connector on one
end, and a custom submarine connector for the M28 on the other.
To charge the M28, simply remove the cable connector plug,
insert the connector from the charger cable, and hand tighten the nut.
Connect the USB interface to a standard USB power source.
The power source can be any USB connection providing 5.1V and a
minimum current of 1.5 Amp. If the LED is ashing alternating green and
red for at least 1 minute, it is most likely that the USB power supply’s
current is insufcient.
